Updated `walletInitSteps` and `settingsSteps` properly: `settingsSteps.py` was referring to some `wallet_init_steps` methods but it was not imported. Reorganization and cleanup.
Renamed `startupSteps.py` to `commonInitSteps.py`.
Cleanup `Processes` folder (not used).
Moved `walletInitSteps.py` inside the own suite steps.
Added files flow diagram.
Closes#8353
- Created `bdd_hooks` that contain the sing up steps just only once in the feature start and the needed start steps depending on the test case.
- Updated feature files removing sign up steps and given/when/then reorganization.
Closes#8026
- Created new `suite_wallet` where all related wallet tests will be migrated to.
- `tst_wallet` has been moved to new `suite_wallet`.
- `tst_transaction` has been moved to new `suite_wallet`.
Tests inside `suite_wallet` still contain some broken tests.
Closes#7627
